Jordan Edwards' father says in a lawsuit that former Balch Springs police officer Roy Oliver used excessive force when he fatally shot the 15-year-old on April 29 as he left a house party.

In the federal suit filed Friday, Odell Edwards complained that after Oliver fired his rifle at the car carrying Jordan, Balch Springs police unlawfully detained the driver, Jordan's stepbrother Vidal Allen. The suit alleges that police called Vidal the N-word and put him in handcuffs after the teen witnessed Jordan being shot in the head.

The complaint also targets the Balch Springs Police Department, which the teen's father says failed to properly train and supervise Oliver.

Balch Springs police Chief Jonathan Haber fired Oliver on Tuesday, three days after the fatal encounter with Jordan. Haber said Oliver had violated policies, but he declined to elaborate.

On Friday, Oliver was arrested on a murder charge. The 37-year-old turned himself in at the Parker County Jail and posted bond a few hours later.

Oliver's attorney wasn't immediately available for comment Sunday.

"Defendant Oliver's violent temper, a fact defendant city of Balch Springs was aware of or should have been aware of, led to the wrongful death of Edwards," the suit reads. "Despite defendant Oliver's conduct prior to Edwards' death, he remained a Balch Springs Police officer and was not terminated despite his conduct and multiple violations of departmental policies."

The suit references a 16-day suspension in 2013 after the Dallas County district attorney's office complained about Oliver's conduct during a drunken-driving case.

Citing a news report, Edwards detailed prosecutors' complaint: The office had a hard time getting Oliver to attend trial, he was angry that he had to be there and used vulgar language so offensive that an assistant district attorney sent a female intern out of the room.

According to the suit, prosecutors texted one another about how Oliver's behavior was scaring them, and at one point — while he was on the stand — he used profanity to reply to a prosecutor: "I don't understand the [expletive] question."

Edwards also cites two other incidents. The first was recorded in a January evaluation in Oliver's personnel file and involved a reprimand against him for being "disrespectful to a civilian on a call."

Another complaint came in April, two weeks before Jordan's death, that alleged Oliver had pulled out his gun after his truck was rear-ended along South Cockrell Hill Road in Dallas. Oliver was off duty.

"As soon as I put my gear into park, he was already out of his truck, and he was at my window," Monique Arredondo, 26, told The Dallas Morning News. "He pulled out his gun on me."

A Dallas police spokeswoman said that when officers arrived at the scene, Oliver had his gun holstered on his hip and a police badge clipped to his belt. He told Dallas officers that he had his gun at the "low ready" and had identified himself as an officer because he thought the other driver may have been reaching for a weapon or trying to flee. Dallas police determined that no offense had occurred.

Nevertheless, Arredondo filed a complaint against Oliver for his "violent behavior," according to Edwards' suit.

Edwards has asked a federal court for a jury trial and for monetary damages tied to funeral and burial expenses, mental anguish and loss of future earnings, among other things. The suit doesn't specify an amount.

Jordan's death sent shock waves across the country. His name has been added to a list of fatalities that has people nationwide debating whether racial bias may have played a role in the killings of unarmed black people at the hands of police.

Haber, the Balch Springs police chief, originally said that an officer had fired his gun because the car that carried Jordan had "aggressively" backed toward police responding to a house party on Baron Drive. But a day later, after reviewing body camera footage, Haber said things had unfolded differently: The car had backed up but was driving away from police when Oliver fired the shot that killed Jordan.

There were three other people in the car besides Jordan and his stepbrother Vidal — Jordan's brother Kevon and two friends who are twin brothers. All the boys are in their teens.

Edwards' lawsuit describes what his family says happened the night of the shooting:

The boys arrived at the party about 9 p.m. on April 29. They made their way to the backyard, where they spent the evening. About 11 p.m., someone announced that police were on their way, and the crowd began to disperse, according to the suit. The boys jumped the fence to get to their car on Baron Drive more quickly.

When Vidal tried to drive off, he noticed a congestion of cars and police officers behind him. He tried to maneuver out of his parking spot near Shepherd Lane and heard what sounded like gunshots. The lawsuit alleges that as Vidal pulled forward ahead of the officers, he heard someone shout, "Stop the [expletive] car!"

Before Vidal could react, Oliver began shooting a rifle as the teen tried to drive away, according to his stepfather's complaint. Edwards said one bullet struck Jordan in the head with such force that it caused the teen to land on Vidal's shoulder.

Fearing for his life, Vidal drove to a nearby street and called Edwards to tell him that Jordan had been shot, according to the suit. Vidal said several squad cars surrounded them.

Police ordered Vidal to throw his phone out of the car, step out and face forward, away from officers, the suit reads. He was told to move to his left, but he inadvertently moved to his right.

That's when, according to the suit, Vidal heard an officer say, "This [N-word] doesn't know his [expletive] left from his right." The teen told his family that he was instructed to walk backward.

Officers handcuffed Vidal and issued similar instructions to the other passengers in the car, according to the suit.

On Thursday, a Balch Springs police spokesman said department officials were still reviewing video from that night but that they hadn't heard racial slurs on the footage they had watched.
